There was this initial issue with delivery. I'm not sure if it was the courier company or the seller but fortunately for me the item arrived just before Christmas. So what was supposed to be a normal purchase turned out to be an addition to Christmas present for my kid!
Three days after Christmas I can confirm that this is the only toy my kid has been playing with since Christmas. He has not put it down at all. The track set does what is says in description. You also get a car along with the set so that you are not left without a car that runs on the track. Infact, like every kid, my Son has a lot of small cars that would easily run on this track. The problem with other cars is that they are not fast enough to run on the track. They would fall off when they go through the revolution bit. We tried all cars that my son has and found that only the ones with fast wheels run on the track (mainly hot wheels). Also the car has to be well balanced i.e an open top car(convertible) would not revolve. I don't know if it has to do with aerodynamics. Similarly a car shaped like an SUV, MUV would not revolve. Only a car shaped as sedan, race car would easily complete the track.
